FRAME FOR BUCKSAWS.

SPECIFICATION forming part of Letters Patent No. 257,701, dated May 9, 1882.

Application filed September 30, 1'881. (ModeLl To all whom it may concern:

Be it known that I, FREDERICK L. HEM- MER, of East Arlington, in the county of Bennington and State of Vermont, have invented certain useful Improvements in Frames for Bucksaws, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,-forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation, partly in section, of my improved saw-frame. Fig. 2 is a bottom view of the cross-piece; and Fig. 3 is a section thereof, takenon the lineman of Fig. 1.

Arepresents the head, and A represents the handle piece,of the saw-frame, which pieces are tied together at their upper ends by the tie-rod B. In the frame, below this tie-rod, is placed the curved cross-piece G, and below this cross-piece are placed the braces D D, which reach from near the centerof the length of the cross-piece G diagonally down to about the center of the length of the head and handle pieces of the frame, as shown clearlyin the drawings. The braces D D are adapted to be moved apart equally in opposite directions for tightening the saw-blade E by means of the right and left hand screwbolt F, which is placed between their adjacent ends, as shown in Fig. 1. The adjacent ends of the braces D D are faced with the curved plates d d, which are formed with a screw-opening for the passage of the ends of the screw-rod F, and the upper ends of these plates are formed with the narrow projections or studs i t', which fit and move in the slots 6 e of the plate a, secured in proper position upon the under side of the curved cross-piece 0. By this means the upperends of the braces D Dare held and guided in the longitudinal movement given to them by the screw-bolt F, theirlower ends being held in suitable mortises made in the head and handle pieces of the frame. The screw-bolt F is provided in its center with the nut f, to which awrench is applied for turning the bolt forbraeing or loosening the saw in the frame.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentlhe braces D D, having the plates at (1, provided with the projections or studs it, in combination with the slotted plate (0 and the right and left hand screw-bolt F, substantially as and for the purposes set forth.

FREDERICK LOUIS HE MMER.
